COMBINED BROILING-FUBNACE AND COOKING-RANGE.

To all whom it may concern:

Be it known that I, VILLIADI Rnson, of Cincinnati, Ohio, have invented anew and useful Arrangement of Broiling-Furnace in Cooking Ranges orStoves; and I hereby declare the following to be a full and eX- actdescription of the same, reference being had to the accompanyingdrawing, making part of this specification.

This invention relates to an arrangement, in a stove or range burningbituminous coal, of a charcoal grate, which after having its contentsignited from the main grate, can be isolated therefrom.

In the accompanying drawings Figure 1 is a perspective view exhibitingthe char coal grate in communication with the main grate; the lid of theformer being removed in order to show the interior. Fig. 2 is alongitudinal section of the same. Fig. 3 is a transverse section,exhibiting the action of the broiling furnace, when disconnected fromthe main firej A, is the principal grate; in which mineral coal isburned.

B, is the broiling, or charcoal grate, having a lid Z).

G, is a passage leading from the grate A, to the grate B. This passagemay be closed at pleasure by the damper c.

E, is a draft hole to the charcoal grate,

which may be closed by a door 6.

F, is an escape flue of the main grate.

G, is the escape fine of the charcoal grate. These escape fines areprovided with the customary sliding dampers.

The operation is as follows: The fire in the main grate A, being inactive combustion, the grate B, is supplied wit-h charcoal and coveredwith the lid .7). The damper 0, being then open-ed, flame from the maingrate passes through the charcoal and ignites it. This being effected,the damper c, is closed, and a draft being now established in thecharcoal fire through its proper passages, it burns as a distinct fire,free from any contamination by smoke or smut from the main fire :anecessary precaution for broiling purposes, where bituminous coal isburned in the main grate.

I claim as new and of my invention herein v The described arrangement ofthe grates A, and B, passages C, F, G, and dampers c, or theirequivalents operating as set forth to temporarily connect the charcoalgrate with the main fire so as to ignite its contents; and afterwarddisconnect them so as to burn independently.

In testimony of which invention I hereunto set my hand.
